The cost in dollars to produce x shovels in a factory is given by the function C(x)=12x+450. The number of shovels that can be produced in h hours is given by the function N(h)=40h. 1. Find the rule for C(N(h)).

2. Find the rule for when h=8 hours.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
